Abstract

Purpose: This study was designed to compare the accommodative amplitude whose 40s initial presbyopia patients divided into five occupation (driver, official worker, housewife, field worker, teacher). Methods: Both "push-up"and "inus lens to blur technique" methods were used to examine the average of accommodative amplitude. Results: All the average of accommodative amplitude (OD, OS, and OU) were the lowest in official worker group (3.27${\pm}$0.21D, 3.31${\pm}$0.22D, 3.54${\pm}$0.28D) and the highest in housewife group (4.07${\pm}$0.35D, 4.11${\pm}$0.35D, 4.37${\pm}$0.39D). Conclusions: Because occupational specifications including a fixative habit are able to change the binocular accommodation, it is important to understand thoroughly the patient's occupation when opticians make near vision prescription for initial presbyopia.

목적: 40대 초기 노안을 대상으로 작업환경이 다른 직업(운전자, 사무직, 주부, 현장직, 교사)에 따른 조절력의 변화양상을 비교하고자 하였다. 방법: "푸쉬업(Push-up)" 방법과 "마이너스렌즈 부가"법을 이용하여 검사하고 직업별 평균 조절력(OD, OS, OU)을 비교하였다. 결과: 사무직(3.27${\pm}$0.21D, 3.31${\pm}$0.22D, 3.54${\pm}$0.28D)이 우안, 좌안, 양안 모두에서 평균조절력이 가장 낮게 측정이 되었고, 주부(4.07${\pm}$0.35D, 4.11${\pm}$0.35D, 4.37${\pm}$0.39D)가 우안, 좌안, 양안 모두 높게 측정이 되었다. 결론: 직업과 그에 따른 주시습관에 따라 눈의 조절력이 달라진다는 사실을 숙지하고, 노안 검사 시 피검자의 직업에 대한 사항을 고려하여야 한다.
